Now a days, sandwich beams and plates made of functionally graded (FG) materials are
widely used in many engineering industries. Therefore, several modeling techniques and …

Functionally graded materials (FGMs) are novel materials whose properties change
gradually with respect to their dimensions. It is the advanced development of formerly used …

This paper studies the nonlinear free vibration of a multi-layer polymer nanocomposite beam
reinforced by graphene platelets (GPLs) non-uniformly distributed along the thickness …

In the present work, free vibration of beams made of imperfect functionally graded materials
(FGMs) including porosities is investigated. Because of faults during process of manufacture …

Static bending and free vibration of functionally graded (FG) microbeams are examined in
this paper based on the modified couple stress theory (MCST) and various higher order …

In the current paper, a new first-order Timoshenko's theory (N-FSDBT) based on the
indefinite integral is proposed to examine the vibrational behavior of power-law (P-FG) …

For static bending and free vibration analysis of functionally graded (FG) sandwich plates, a
novel, enhanced first-order mixed plate element (IMQ4) is developed in this work. The …

Finite element model for vibration and buckling of functionally graded sandwich beams
based on a refined shear deformation theory is presented. The core of sandwich beam is …

This paper proposes a new higher-order shear deformation theory for buckling and free
vibration analysis of isotropic and functionally graded (FG) sandwich beams. The present …

In the present paper, a novel refined shear deformation beam theory is proposed and
applied, for the first time, to investigate the bending behavior of functionally graded (FG) …
